Attempting to set a SAVEPOINT when one of the involved storage engines does not support savepoints, raises an error, and results in statement rollback. If Galera is enabled with binlog emulation, the above scenario was not handled correctly, and resulted in cluster wide inconsistency. The problem was in wsrep_register_binlog_handler(), which is called towards the beginning of SAVEPOINT execution. This function is supposed to mark the beginning of statement position in trx cache through `set_prev_position()`. However, it did so only on condition that `get_prev_position()` returns `MY_OFF_T_UNDEF`. This before statement position is typically reset to undefined at the end of statement in `binlog_commit()` / `binlog_rollback()`. However that's not the case with Galera and binlog emulation, for which binlog commit / rollback hooks are not called due to the optimization that avoids internal 2PC (MDEV-16509).

MariaDB: The open source relational database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:

Help
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss, MariaDB's Zulip instance, https://mariadb.zulipchat.com/
Live QA for beginner contributors
MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions they’d like, and a live developer will be available to assist.
New contributors can ask questions any time, but we will provide immediate feedback during that interval.
